Liatrio - Principal Application Modernization Engineer
Requirements
• Engineering and Architecture • You have a track record of owning the architectural direction of complex workstreams in enterprise environments — you've made the hard technical calls, been accountable for the outcomes, and learned from the experiences that didn't go as planned • You've modernized large legacy applications in real enterprise environments — you understand the strangler fig pattern, incremental refactoring, and event-driven decomposition as practical strategies you've applied under real constraints • You're fluent across the full delivery stack — frontend, backend, APIs, data, cloud infrastructure — with genuine depth in multiple areas • You've designed and delivered cloud-native, distributed systems at enterprise scale — microservices, event-driven architectures, API gateways, async messaging — and you understand the failure modes and operational complexity that comes with them • You've operated in large enterprise environments with multi-cloud setups, complex organizational structures, and legacy constraints — and you know how to deliver meaningful progress despite them • You can hold the technical bar for an entire workstream — reviewing architecture, reviewing code, catching problems early, and developing engineers through the process • You have enough knowledge of platform engineering, infrastructure as code, cloud-native platform adoption — whether that's Kubernetes, managed container services, or other orchestration platforms depending on client environment — and DevOps practices to make good architectural decisions and speak credibly to the engineers responsible for the platform • AI and Intelligent Systems • You've built or integrated AI capabilities — you understand the full picture from integration through deployment, observability, and the ongoing work of keeping AI-powered features reliable • You can have a credible conversation with client technical leaders about where AI creates genuine leverage — grounded in what's real • 8+ years of hands-on software engineering experience, with demonstrated ownership of complex technical workstreams • Must be authorized to work in the United States or Canada without sponsorship • Travel availability: 25-50% depending on client needs • Full benefits including unlimited PTO, funded HSA option, 401k match, monthly LiveWell stipend, and quarterly company bonus • Annual base salary: $170,000 - $200,000 depending on experience • We may use artificial intelligence (AI) tools to support parts of the hiring process, such as reviewing applications, analyzing resumes, or assessing responses. These tools assist our recruitment team but do not replace human judgment. Final hiring decisions are ultimately made by humans.

Responsibilities
• Technical Ownership and Architecture • Define the scope of technical work related to deliverables and milestones of the engagement • Own the architectural direction of your workstream — making key technical decisions, documenting tradeoffs, and ensuring the team is building toward something coherent and maintainable • Responsible for code quality, architecture, and technical direction across the team • Write and review production code across the stack — your technical judgment sets the bar, and you're in the work alongside the team • Integrate AI and LLM capabilities into client applications — designing the architecture for agentic workflows, RAG pipelines, intelligent automation, and AI-augmented developer tooling, and guiding your team through implementation • Anticipate technical risk before it becomes delivery risk — surface issues early, define mitigation strategies, and communicate proactively • Participate in scoping discussions and SOW architecture for new and existing customers • Generate ideas, be willing to fail fast, and demonstrate with POCs • Drive knowledge sharing in and out of client engagements • Client Technical Engagement • Serve as the senior technical point of contact for your workstream — engaging directly with client engineering managers and directors on architecture, delivery strategy, and technical risk • Build trusted relationships with client technical leaders • Proactively identify opportunities to improve engineering practices and technical quality at the client, and drive that change • Participate in business development including client expansion conversations and SOW development • Team Leadership and Development • Responsible and accountable for the technical outcomes of your team • Write monthly feedback for all engineers on your workstream in collaboration with the Delivery Lead • Mentor engineers through real technical challenges — pairing on hard problems, reviewing architecture decisions, giving feedback that raises their game • Organize and break down complex work so the team can execute with clarity
